Joe, Eli and Kai had the same number of notes. Joe and Eli had a mix of $50-notes and $5-notes. Eli had 9 $50-notes while Joe had 18 $50-notes. Kai only had $50-notes.
- Who had the least amount of money?
- How much less did Eli have than Joe?
- Joe used all his $5-notes to buy a wallet. He then had $1200 less than Kai. How many $50-notes did Kai have?
(a)
The three boys had the same number of notes.
$50-notes have a higher denomination than $5-notes.
Since Eli had the least number of $50-notes, he had the least money.
(b)
Number of less $50-notes that Eli had than Joe
= 18 - 9
= 9
Difference in the value of $50-note and $5-note
= 50 - 5
= $45
Amount that Eli had less than Joe
= 9 x 45
= $405
(c)
Value of $50-notes that Joe had left
= 18 x 50
= $900
Total value that Kai had
= 900 + 1200
= $2100
Number of $50-notes that Kai had
= 2100 ÷ 50
= 42
Answer(s): (a) Eli; (b) $405; (c) 42
